Which calculator do I need?
Five tools, five different questions.
  • Buy vs Rent (free) — should I buy at all, or rent and invest the difference? Compares net worth under both paths over time.
  • Mortgage Calculator Pro (premium) — what does one specific loan cost over time? Full amortization, ARM resets, balloon payments, prepayment plans (extra, lump-sum, biweekly), and early-payoff penalty costs (common on rental-property loans).
  • Refinance Lab (premium) — should I swap my existing mortgage for a new one, and when do I break even on the closing costs?
  • Short-Term Rental ROI (premium) — would this property work as a vacation rental? Revenue, occupancy, seasonality, cash-on-cash, and break-even occupancy.
